Answer:
See below
Step-by-step explanation:
Expand L side to get
4n -12 -2n < -10 + 2n simplify L side
2n -12 < -10 +2n subtract 2n from both sides
<u>-12 < -10 </u> <===== so the equation is true for ALL n
(-∞ , + ∞ )
Answer:
2.) 0.10 (3.) 0.10 (4.) 2.43
Step-by-step explanation:
Given that:
x p(x)
0 0.12
1 0.18
2 0.30
3 0.15
4
5 0.10
6 0.05
X : __0__ 1 ___ 2 ___ 3 _____ 4 ____ 5 ____ 6
p(x):0.12_0.18_0.30_0.15__0.10___0.10 ___0.05
Σ of p(x) = 1
(0.12 + 0.18 + 0.30 + 0.15 + x + 0.10 + 0.05) = 1
0.9 + x = 1
x = 1 - 0.9
x = 0.1
2.)
P(x = 4) = 0.10
3.)
P(x = 5) = 0.10
4.)
Σ(x * p(x)) :
(0*0.12) + (1*0.18) + (2*0.3) + (3*0.15) + (4*0.1) + (5*0.1) + (6*0.05) = 2.43
Answer:
x=-2
Step-by-step explanation:
-4x - 8 = -4 • (x + 2)
Do you have any options of the equivalent expressions or is it just a plan question that you just asked?
The value of angle x is 53° for the given triangle.
<h3>What is
angle?</h3>
An angle is the formed when two straight lines meet at one point, it is denoted by θ.
In the given isosceles triangle,
one angle is 74°,
Since, two sides of the isosceles triangle are equal, so the corresponding angles will be equal to x.
The sum of angles of a triangle = 180°
x + x + 74 = 180
2x = 106
x = 53
The required value of angle x is 53°.
